Abstract

In producing a product in the industry, it is necessary to pass a series of processes, one of which is in the printing process or die casting. After installation of casting molds (Fix Dies & Moving Dies), it is necessary to set the fast shot & slow shot valve rotation to determine the amount that pushes the molten liquid into the mold, so the casting machine is ready to use. At this time the Fast Shot & Slow Shot Valve setting process is still done manually (conventional), the technician must make a rotation manually and only look at the value of the needle available on the knob, therefore we need a modification on the control system that can facilitate in doing setting the valve. By using the Stepper motor Nema 17 as the output of the Omron CP1L-M30DT-D PLC and also using Encoder E6B2-CWZ6C as an input that has been calibrated, so that the round reading can be seen in HMI Omron NB7W-TW00B. Obtained a fast cycle time results, namely in moving 1 round of knob, it takes 0.6 seconds.

Abstract

Sekolah merupakan tempat yang dirancang untuk proses pembelajaran dan pembentukan karakter bagi siswa. Sekolah perlu dievaluasi untuk mendapatkan kualitas pendidikan yang layak. Kondisi aktual, di area Penajam Paser Utara masih terdapat beberapa sekolah yang masih dibawah rata-rata. Pengabdian ini bertujuan untuk mengevaluasi sekolah binaan YPA-MDR dan memberikan saran pengembangan untuk program sekolah ke depannya. Metode yang digunakan dimulai dengan pendampingan, assesmen dan pengembangan. Setelah pembinaan suatu program atau kegiatan, evaluasi dilakukan untuk menilai efektivitas serta menggali potensi pengembangan yang ada. Hasil pengabdian menunjukkan bahwa terdapat kenaikan level asesmen sebesar 86.67 %, terdapat 13.33 % jumlah sekolah yang levelnya masih tetap (belum terdapat perubahan) dari tahun sebelumnya dan tidak ada sekolah yang mengalami penurunan. Secara menyeluruh pengembangan untuk sekolah adalah perlu pengenalan metodologi PDCA untuk program sekolah yang teratur, perlu standarisasi notulensi rapat yang mengakomodir PICA untuk mengetahui permasalahan dan solusi perbaikan serta perlunya pelatihan penggunaan tools seperti Ms. Office Excel.

Abstract

The increasing demand for renewable energy requires efficient power conversion and control strategies to maximize the utilization of photovoltaic (PV) systems. Among various approaches, Maximum Power Point Tracking (MPPT) is critical in ensuring optimal energy extraction under varying irradiance and load conditions. This study focuses on optimizing the efficiency of the Perturb and Observe (P&O) algorithm implemented in a PV array system with a DC–DC boost converter. A comprehensive Simulink-based investigation is conducted to analyze the algorithm’s performance in terms of tracking speed, stability, and steady-state oscillation. The results demonstrate that the optimized P&O method significantly improves the dynamic response of the boost converter while maintaining high tracking accuracy under irradiance fluctuations and load variations. Furthermore, this work is presented as a preliminary study prior to the integration of MPPT control with a PLC-based monitoring system, providing a reliable foundation for real-time industrial applications. The findings contribute to the enhancement of PV system efficiency and offer valuable insights for future implementation in smart energy management platforms.
